1. With the integration of GPRS communication technology, the power supply of the communication module can be controlled separately, which can further prevent the data communication module from crashing.

2. It can be connected to various domestic and oversea meter protocols at the same time.

3. Safe and reliable control technology with multi-level protective measures;

4. It has the function of active fault reporting, which can locate and solve the fault instantly.

5. The use of large-capacity electronic disk and embedded file management technology can ensure the preservation of historical data for a long time.

6. Function module remote upgrade and remote maintenance, flexibly meet the requirements of system function expansion in the future;

7. Advanced data compression and encryption technology.
